MRS ARMSTRONG Wayward pupil Trudie Baxter finds herself on the wrong side of battle-axe Miss Armstrong. When Baxter oversleeps one morning and misses the school excursion, Miss Armstrong finds her chores to do. When Trudie refuses, she is spanked over the knee on her bare bottom. She considers this harsh treatment, but her punishment really begins when Head Teacher Alistair Bates returns from the trip. Bates has a no-nonsense approach to these situations and sends for his cane. Baxter is to be caned severely as a lesson to others.
